hi, im poping up a window with:

\<%= link\_to(“Add new Item”, “/bol\_lines/new”, :popup =\> [‘window\_name’,  
‘width=600,height=600’]) %\>

now, that link resides in teh edit view of the parent of the 1\<\>N  
asscoation. the child window is supposed to be the NEW view of the  
child-association. but to submit the new view containting the  
bol\_lines form i need to have the parent\_id as hidden field or  
similar…  
how can i achieve that?
